Authorities say Thaddeus Boone, 22, of Newark, N.J., set the fire Sunday night after an argument with his girlfriend in her Boerum Hill home. The flames left a 5-month-old boy and his 8-year-old sister in critical condition. Their conditions have since been upgraded to stable.

The incident also left two other siblings and their 63­-year-old grandmother with minor injuries.
